LED remains blank until the rebuild is complete. The rebuild percentage displays

Adding Capacity by Adding a Drive

To increase capacity, simply insert an additional drive into the system. The system
does not have to be turned off or disengaged from its work to do this. The WD
Sentinel server automatically recognizes the drive, checks to see if the drive is
approved for use in the WD Sentinel server, and reconfigures the RAID to accept the
new drive. At the completion of this reconfiguration, the additional capacity is
automatically available to the system. No further operation is required.
Note: The additional drive must have a minimum available capacity of the
smallest drive in the array. For example, a 3 TB drive may be added to an
array made up of 2 TB drives, but a 2 TB drive may not be added to an
array composed of 3 TB drives.

2. Unlock the handle on the empty drive bay and insert the drive into the bay,
